The Glow-worm domestic thermistor decreases current resistance as the temperature of the thermistor rises. The printed circuit board sends a current to the thermistor and can tell whether a decrease or increase in temperature is needed by the resistance in the thermistor.

A Glow-worm NTC sensor for Betacom appliances.  The sensor or thermistor decreases circuit resistance in line with temperature increases. A boiler's printed control board (PCB) sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance.
